This invention relates to an apparatus for the convenient transfer of booked entries from a general list of such entries on to classified accounts or registers, and the invention consists in eifecting the transfer by optical means for instance photography, for which purpose the list is fed intermittently through a guideway having an exposure window with which photographic cameras provided with film strips, are selectively aligned, this being efiectedby co-operating con i trolling means on the list and on the guideway.

Means are also provided for transferring an entry on to more 'thanone account or register.

The construction of the apparatus and the means whereby it is operated may be subjected to considerable modifications. In the accompanying drawings the invention is illustrated in connection with an electrically controlled apparatus having means for transferring entries from acontinuous list fed from a delivery on to a take-up roller and provided with apertures whereby the mechanism is controlled.

' Fig. 12 is a plan view of the camera mechanism, partly in section on the line l2-l2 of for the photographic transfer of the entries to their respective accounts or registers. For this purpose a plurality of photographic cameras 8 are in the present instance mounted radiallyin even distribution on a holder in the .form of a Fig. '10 is a side view of the camera mecha- I 35 ni disc 32 which is mounted rotatably on a shaft 82 and constructed as a worm wheel, it being in operative engagement with a worm 3| driven by an electric motor M. The holder 32 is arranged so as to move the cameras in succession through 5 a position of alignment with the window 2|) for photographing the entries appearing in the latter.

The feeding of the list 14 is eifected by means of feed roller pairs [5, i6 and II some of which n have sprockets for engagement in known manner in edge apertures made in the paper strip. The rollers are geared together, and the principal roller I5 is fitted with a spur gear 61 (Fig. 8) which meshes with a gear 86 connected to a ratchet wheel El. A hand lever 55, which is operated once for each entry, rcciprocates, in cooperation with "a spring I, a rod 51 fitted with a pawl 60 which engages the ratchet wheel 6! for rotating the gears and the feed rollers. Each such operation of the lever 56 causes the list I! to be advanced so as to bring a fresh entry into view in the window 20.

On its way to the feed rollers, the list It passes across a tracker bar [,9 which is suitably connected to a source of suction and which is provided with a row of apertures. For each entry on the list to be transferred, there is oh the list an aperture which registers with one of the apertures on the tracker bar when the respective entry is exposed in the window 20. A block 9 between which "and the tracker bar the list It passes,'is provided with channels-which register with the apertures in they tracker bar. These channels are controlled by a rotary three-way valve 8, and a pinion 59 connected to the valve meshes with a gear wheel or sector 58 which is connected to the bar 51 so as to be rocked by the latter. On the lever 56 being moved into the position shown in Fig. 8, the ratchet wheel 6| is turned for advancing the list i4, and at the same time the valve, 6 is turned so as to form straight channels through the block 9. When the hand lever returns to its initial position, the outer ends of the channels are con- 4 necte'd through passages III with the atmosphere.

At the outer end of the blocks the channels terminate in pipe connections l2 which communicate through pipes II and through pipe connections I6 with cylinders 22 \secured in uniform distribution to the circumference of a circulan frame 21 which is coaxial with and arranged near the rotary camera holder 32. The latter is fitted with two electric contact rings 28 and 29 which are swept by an arm- 30 connected to the 55 it will be seen that the rings 28 and 29 are connected to the positive pole of an electric source and that the motor M is fed with current through a circuit traced through the leads a and b, the rings 28, 28, the arm 36, alead c, a sliding contact 14, and leads (I and e. Thus the motor and holder 32-will be maintained in motion when the circuit is closed by a switch 15. Under each cylinder 22 (Fig. 6) there is a gap in the ring 29' which gap is normally filled in with a segment 25 carried by a double-armed lever 33. controlled rod 11 to a piston 23 located in the vcylinder 22. When an aperture in the list It is in register with one of the channels in the block 9, suction will be applied to the respective cylinder 22, and the piston 23 will then be raised so as to lift the segment 25 from its position in the ring 29 and break the continuity of the latter. Opposite the gap in the ring 29 there is a patch of insulation on the ring'28 so that, when the arm 30 arrives at the gap, the motor circuit will be broken and the camera holder 32 will come to a standstill. When this happens, one of the cameras 8 will be. in alignment with the window 20 for photographing the entry appearing in the latter.

Each camera contains a film strip 82 (Fig. 10) whereon the entries are photographed. The strip is fed from a spool 18 on to a spool 19 by means of a feed roller 46 which, together with a guide roller 80,- holds a portion of the strip in the focal plane of the camera lens 54. The roller 46 is connected to a ratchet Wheel 45 which is engaged by a pawl 44 connected to an operating lever 43. The latter carries the armature of an electromagnet 42 which actuates the lever and which is energized in the following manner:

An electro-magnet 36 is mounted in a stationary position within the circular path traced by the cameras and arranged so as to be in alignment with any camera thatstops in front of the exposure window 20. The armature of the magnet is connected to a spring-controlled rod 31 carrying two electric contacts 38 and 3% which are connected to the electric source and which, when the armature is attracted by the magnet, are moved into engagement with corresponding contacts 4|] and 4| carried by the camera in front of them. The contact arm as of the camera holder 32 is fitted with a contact 35 (Fig. 6) which is connected by a lead f (Fig. 13) to a sliding contact 8| which in its turn is'connected through the magnet 36 with the positive pole of the elec- 'tric' source. The lever 33 carries a contact 341 which is connected to the negative pole of the source and which, when the lever is operated for breaking the continuity of the contact ring 2t, is moved into position to be engaged by the contact 35. Thus, as the circuit of the motor M is broken, the circuit of the magnet 36 will be closed through the leads a and g, magnet 36, lead h, contact 8!, lead 1, contacts 35 and 34, and leads 'i and e. The rod 31 is then thrust forwards by the armature of the magnet 36, and as the contacts 38 and 39 engage the contacts 48 and 4!, the.

following circuit will be closed: Leads a and k, contacts 39 and 4 I, magnet 42, contacts Wand 38, The armature of the magnet 42 will then be attracted, and the ratchet wheel 45 will be operated for feeding the film strip one step,

forward. As the lever 43 is rocked for this purpose it connects by means of a contact 41 two leads and p and thus closes a further circuit The latter is connected by a spring-- acclaim holder 32. Referring to the diagram in Fig. 13

through the contact 4! a lead n, a magnet 4|, the lead 9, the contact 41, the lead 0 and the contact 40, and the magnet 48, on attracting its armature, operates a spring-controlled lever 49 and a pawl 50 so as to turn a ratchet wheel The latter acts by means of a conical gear 52 on a rotary shutter 53 by which the lens aperture is momentarily cleared for making the photographic ex posure. On the hand lever 56 being restored to its initial position, the valve 6 sets the cylinder in communication with the atmosphere, whereupon all the other elements are also restored by their springs to normal position, ready for the next exposure. Apilot lamp 55 arranged in the lead 1 lights up to indicate that the photographic mechanism is in operation.

It may be desired to transfer an entry on to more than one register, and for this purpose the following arrangement is provided:

Referring to Fig. 5 it will be seen that the feed roller I5 transmits motion to the rollers l6 and l! through the medium of a shaft 64 and a set of conical gears. The driving gears 83 and 84 for the rollers l6 and I! are mounted ona sleeve 65 which is loosely arranged on the shaft 84 and coupled to the latter through the medium of a spring barrel 69. The lattcr has a toothed rim 10, and a spring-controlled plunger 68 is adapted to be urged by a magnet H into engagement with the rim so as to prevent the spring barrel and thus the feed rollers l8 and H from moving. When this happens, and when the hand lever 5% is operated for feeding the list across the tracker bar IS, the resulting operation of the camera mechanism will be to move two or more cameras successively into position to receive the image of the entry retained in the window 20. In the meantime the list l4 will be slackened between the feed rollers 15 and 16, but as soon as the spring barrel BS is released, it will even out the slack. For the automatic operation of the plunger 68, the following arrangement is provided:

A spring-controlled feeler I2 (Fig. 9) is pivoted to the blbck 9 and arranged to bear against the list l4 opposite a contact member 2 (Fig. 13) let into the tracker bar N. For each entry on the list to be thus transferred to several registers, the

- list is provided with an aperture allowing the feeler 12 to touch the contact 2, and a circuit will then be closed through the lead a, the magnet a lead q, the contact 2, feeler 12, a lead r,-

and the lead e. The magnet 1| then operates so as to retain the particular entry in the exposure window for repeated exposures. If more than two exposures are to be made from the same entry, the respective apertures in the list may be combined into a single, elongated aperture. As soon as the list again intervenes between the contact member 2 and the feeler '12, the spring 'barrel 69 will be released.

The photographic negatives obtained in this manner are subsequently printed and may be suitably enlarged.

The apparatus may be subjected to modifications within the scope of the invention as defined by the appended claims. For instance the entries to be transferred may be made on cards passed in succession through the guideway. The controlling apertures in the list may be replaced by metallic contacts for closing the different circuits, and means may be provided for moving the guideway relative to the group of cameras instead of vice versa.
